近年来,由于温室无土育秧比带土育秧既省工又经济,因而得到了迅速发展.无土育秧其秧龄只有6～8天,苗高8～10公分,根呈盘状.这种又小、又细、又嫩的秧苗,用人工栽插既费力效率又低,那么能否用机器来栽插呢?两年来,我们经多次试插研究结果表明,只要稍为改装和恰当地调整机器,并注意农艺要求,无土育成的秧苗不但可以机器栽插,且其栽插质量不比洗根大苗差(见表).现根据我们的实践,就如何插好无土秧苗,谈谈其主要技术措施. 使用与调整取秧滑道由于无土所育之秧苗根短并呈盘状,所以秧爪入帘高度要低.上海-Ⅰ型机动插秧机选用20毫米的取秧滑道较适宜,而东风-2S型机动插秧机的三种
In recent years, due to greenhouse soilless seedling than earthy seedlings both labor and economy, which has been rapid development of soilless seedling its seedling age is only 6 to 8 days, the height of 8 to 10 cm, the root was disk-shaped. Small, thin, and tender seedlings, artificial planting is both laborious and low efficiency, then the machine can be used to planted it? Two years, we have repeatedly inserted interpolation study results show that as long as slightly modified and properly adjusted Machines, and pay attention to agronomic requirements, soilless seedlings not only can be planted machine, and its planting quality is better than the root washing seedlings poor (see table.) Now according to our practice, how to plug in soilless seedlings, talk about its The main technical measures .Use and adjust the pick-raising slide due to soilless nursery seedling root is short and was disk-shaped, so the seedling claw into the curtain height is low. Shanghai-I type portable transplanter selection of 20mm slippery road Suitable, and Dongfeng -2S three kinds of mobile transplanter
